Just updated my BB to the latest firmware, and all hell is breaking loose with this time signature change. The issues are:
My ROLAND SY300 keeps telling me that it is receiving bulk data, even though it is on a different channel.
My message to the downstream devices are not always getting there, they get interrupted by this time signature sync thing. If I turn off time signature sync, everything works as expected.
This started happening as of the latest update to BB.
